Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed November 11, 1909. Serial No. 527,557.

subject of the German Emperor, residing at Stapleton, in thecounty of' Richmond and State of New York, have invented new and useful Improvements in Bag-Machines, of which the following is a specification.

My. invention relates to bag. machines and the object of my invention is to produce" an automatic mechanism which will print, fold, out and sew fabric into bags.

In the accompanying drawings I have shown a double machine but have omitted many of the duplicate parts.

Fig. 30 is an enlarged view of the pressure lever 12. Fig. 31 is a sectional viewtaken on the line OO of Fig. 1 showing the speed regulating mechanism for controlling the feed of the web of cloth from the printing press to the cutting mechanism. Fig. 32 is a detail sectionalview on the line P-P of Fig. 2 show- 'ing the folding mechanism and electrical mechanismfor maintaining the folder in the center of the web of cloth. Fig. 33 is a sectional view on the line R-R of Fig. 32.

84 is a diagrammatic view of the electrical mechanism for maintaining the folder in the center of the web of cloth. Fig. 35 is a diagrammatic view of the switch mechanismfor reversing the motor.

In the accompanying drawings similar letters of reference refer to similar parts. v The fabric is fed' to the machine from a roll 1 which is supported on a roller 1: mounted in suit-able bearings in the frame 2 of the machine. From the roll the web of cloth passes over a rod 3 and under another rod 4 both of which are secured in the frames From thence it passes ,un

against rotation. der the rod 5 and over the rod 6, these rods being mounted against rotation in opposite ends of the corresponding plates 7 secured to either side of the frame 2 by bolts 8 and lock-nutsB. This construction renders it possible toadjust and secure the plates 7 in any desired position and thus regulate the press.

tension on the web of cloth; from thence the cloth is carried over a series of idle rolls 9 mounted in suitable bearings in the frame 2, and adapted to rotate therein; thence between the feed rolls 10 and 11, mounted in suitable bearings in the frame 14.

Resting on the top of the feed roll 10 are levers 12 one end of which .engages with shoulders 13 on the frame 14 of the printing To the outer end of the lever is secured a weight 15 by means of a cable 16 which is secured in notches 17, the pressure of the lever being regulated by shifting the cableto the desired notch in the lever. By the mechanism described, the pressure of the roll 10 uponthe fabric passing under the roll 10 and over the roll 11 is regulated so as to compel the fabric to feed with the rotation of the rolls. From thence the fabric passes under the rod 18 which is secured against rotation in the frame 14 of the printing press, under the idle roll 19, over the idle roll 20 andover the driven printing roll 21 all of which rolls are mounted in suitable bearings in the frame 14. The roll 21 is engraved with the matter to be printed upon.

the fabric and is mounted in a trough 22 secured to the frame 14 and partially filled with ink. On one side of this trough is mounted a scraper 23 which plays against the surface of the printing roll and removes therefrom. any surplus ink which may adhere to the surface, thereof. Mounted just above the printing roll 21 is a driven roll 24 provided with flexible shoes 25 of rubber or other suitable material adapted to force the fabric against thesurface of the printing roll 21, whenever an impression is to be printed upon the fabric, and as these shoes do not extend all around the roll 24, the tension on the fabric will lift it away from the roll 21 at all other times. The roll 24 is mcunted in suitable bearings in the frame 14. From thence the fabric passes around the idle roll 26 mounted insuitable bearings in the frame 14 through slots 26 -and over the rod 27 which is non-rotatably mounted in a frame 28, supported on the main frame of the machine, thence over the rod 29 which is mounted on said frame 28' against rotafroma bracket 35 supported on the main frame 2 is a rod 36 having a forked end37 through which. the end ofthe blade 33 extends until the pin 34 rests upon the upperface thereof. This forms a support for the;:;

folder 31, the upper rear surface of whi'e rests against a rod 38 supported "in the frame 28. y It is apparent that in order to fold the electrical circuit.

fabric along the middle line thereof that the center line of the web must be maintained at the lower point of the triangular former. In order to accomplish this result a bracket 39 is mounted on the back of the triangular former 31 and through a suitable opening in this bracket is passed a rod 40 provided with set-rings 41. The rod 40 is also mounted in suitable hearings in plates 42 and 42 secured to the frame 28 and one end of the rod 40 is screw-threaded at 43. Secured to the plate 42 is a small electric motor 44, the shaft of which is provided with a worm 45 adapted to mesh with a gear 46 which is provided with a female thread adapted to engage with the thread 43 on the shaft 40, the gear 46 being locked in position by engagement with the shaft of the motor.

It is apparent that the rotation of the motor in one direction will cause the upper end of the folder 31 to be shifted or tilted from its normal position with the rotation andshifting of the rod 40, and that when the motor is rotated in the opposite direction, the rod 40 will be rotated and shifted and the folder 31 shifted or tilted in the opposite direct-ion. This shifting or tilting of the former 31 causes the web of cloth to shift across its surface and by the proper shifting or tilting of the former 31 the lower forming point thereof may be always maintained at the center line of the web.

In order to provide automatic means for accomplishing this result, I have providedtrailing fingers 47 and 48 which are adapted to rest lightly by gravity upon the edges of the fabric folded over the former 31. These fingers -are respectively mounted on shafts 49 and- 50 and secured thereto by set-screws 47 and 48 The shafts 49 and 50 are mounted in suitable bearings 51 secured to a brace 52 mounted on the frame 28. Also secured to said'shafts 49 and 50 by setscrews 53 and 54 are light depending rods 53'and 54 each of which forms part of an Securedin like manner to the shafts 49and 50 by set-screws 55 and 56 but insulated therefrom by-suit-able insulatingmaterial are light depending arms 55 and 56 provided with forked ends, each. finger of said forks being insulated from the other fingerof the same fork and each finger forming part of an electric circuit. The forked rod 55 is so mounted that the end of the rod 54 will passv between the fingers on the forked end thereof but will normally be out of engagement therewith, and the rod .56 is so mountedthat the end of the depending rod 53 will pass between the fingers on the forked end thereof but will be normally out of engagement therewith, and the forked rods 55v 56 are so off-set that they will not contact with each other. From this construction it is apparent that whenever the
